Psoriasis is a chronic, autoimmune skin disease, causing red, crusty papules all over the body, but mostly on scalp, elbows, knees, trunk. The lesions can merge, forming big patches. In normal, skin cells are updated every time and it usually takes around 3-4 weeks, but in people with psoriasis, the same process can take only 3-7 days, resulting in red, crusty patches. Psoriasis can occur at any age, but is more common among people under 35. Men and women are affected equally. The cause is unknown, it is an immune system disorder, however there are certain factors, that may be a trigger in developing of the disease, such as:

Psoriasis can not be completely treated. Certain medicine, topical and systemic, alongside strict diet may help to have remission and  keep the disease under control. If you have psoriasis, see your dermatologist.
